Mallett was 21-of-33 passing for 380 yards and three touchdowns, and he was at his best in the most pivotal part of the game.

Georgia had scored two touchdowns in the fourth quarter to forge a 24-24 tie. The Razorbacks didn't want to go into overtime with Georgia having all the momentum, and Mallett made sure that didn't happen.

Arkansas took possession of the football on its 27 with 54 seconds remaining. He hit tight end D.J. Williams on completions of 18 and 15 yards to move the ball to Georgia's 40. Then, he rifled a strike to wide receiver Greg Childs, who broke away from the defense and rambled for the winning score.

"This is a surreal feeling," Mallett said after the game. "This has got to be one of the greatest moments I've felt since I've played the game of football. It so rarely comes down to the wire like this."

On the other side of the coin, Washington's Jake Locker's Heisman hopes were dashed in a 56-21 loss to Nebraska in which he went just 4-of-20 passing and threw two interceptions, one of which was returned for a touchdown.

Here is this week's top four.

1. QB Denard Robinson, Michigan: The Wolverines needed another excellent outing from Robinson to avoid an upset at the hands of FCS member Massachusetts. Robinson passed for 241 yards and two touchdowns and rushed for 104 yards and a score in a 42-37 victory. Robinson leads the nation with 559 rushing yards and an average of 410.0 yards in total offense per game.

2. QB Terrelle Pryor, Ohio State: He had his third consecutive game with more than 230 passing yards in a 43-7 rout of Ohio. Pryor threw two touchdown passes and ran 13 yards for another. He even set a school record with 16 consecutive completions.

3. QB Ryan Mallett, Arkansas: Who could ask for more from a quarterback than Mallett delivered against Georgia? He passed for 380 yards and three touchdowns, including a winning 40-yarder in the final seconds.
